GEORGE I. WIGGINTON, OF KALAMAZOO, MICHIGAN, ASSIGNOR TO KALAMAZOO LOOSE LEAF BINDER CO., OF KALAMAZOO, MICHIGAN.

TEMPORARY BINDER.

Specification of Letters Patent.

Patented Oct. 2, 1917.

Application led February 10, 1916. Serial No. 77,492.

To all lwhom t may concern:

Be it known that I, GEORGE I). WIGGIN- TON, a citizen of theUnited States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Temporary Bind ers, of which the following is a specification.

This invention relates to improvements in temporary binders.

The main objects of this invention are:

First, to provide in a temporary binder or loose sheet holder an improved adjusting mechanism.

ISecond, to provide in a temporary binder or loose sheet holder an improved adjusting mechanism which is capable of very accurate or fine adjustments.

Third, to provide an improved temporary binder or loose sheet holder which is capable of rapid manipulation to permit the removal or insertion of sheets or leaves and one which is very secure when adjusted and is simple and compact, so that it may be readily embodied in binders of small size although well adapted foruse in binders of large dimensions.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specilication, in which:

` Figure I is a detail inside plan view of a structure embodying the features of my invention, with the covers extended, the leaves being shown in upright position.

"Fig II is an inverted detail view of the adjusting mechanism of the embodiment shown in Fig. I. Fig. III is `anenlarged detail inverted view similar to that of Fig. II, with the 1 housing or support for the clutch roller removed.'

Fig. IV is an enlarged a line corresponding to the of Figs. I and III, showing details adjusting mechanism.

detail section on broken line l--Li of the Fig. V is a plan view of the blank from which the clutch roller housing or support is formed, the same being made as a sheet metal stamping.

Fig. VA is a detail View of the key employed in the operation of my improved lpirpler when embodied as shown in Figs.

Fig. VI is a detail plan view of a modified form of the adjusting mechanism.

Fig. VII is an inverted detail View of the embodiment shown in Fig. VI.

Fig. VIII is a detail view similar to that of Fig. VII, with the clutch roller housing or support in section.

Fig. IX is a plan view of the blank from which the clutch roller housing or support of the embodiment shown in Figs. VI, VII and VIII is formed. j

Fig. IXA is a detail of the key employed in the manipulation of the mechanism shown in Figs. VI to IX, inclusive.

Fig. X is an inverted detail view similar to that of Fig. VIII, showing another modified form or embodiment of my invention.

Fig. XI is an inverted detail view similar to Fig. VIII of still another embodiment of my invention.

Fig. XII is an inverted detail view, similar to Fig. VIII, of another embodiment or modification of my invention, a clutch block being substituted for` the clutch roller shown in the foregoing figures.

Fig. XIII is a detail section on a line corresponding to line 13--13 of Fig. XII.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the covers 1 and 2 are preferably provided with clamping bars or members 3 pivotally connected thereto as shown in my Patent No. 1,022,- 452, issued to me April 9, 1912. The binding members 4, preferably in the form of flexible strips extend between the covers, being connected to the cover 1 at 5 and to the cover 2 through my improved adjusting mechanism. The cover 2 is provided with a recess or chamber 2 in which the adjusting mechanism is disposed. j

This adjusting mechanism comprises a cross head or adjusting member 6 to which --cover 2.

the binding strips are connected. The adjusting member' is slidably mounted upon the bar 7 disposed longitudinally of the The adjusting member is held in its adjusted position on the bar by means of a clutch which, in the embodiment shown in Figs. l to V, inclusive, consists of a roller 8 having' a segmental toothed portion 9. rlhis clutch roller 8 is supported on the under side of the adjustingmember by the housing 10, which is formed as a sheet metal stamping, and extends across the'bar 7 between the slide loops 11 and has an attaching portion 12 oiiset at 13 to provide a supporting shoulder for the bar. The opposite yend of the housing member 1s vsecured uponthe rack-like .vay lll. This Way ,14 is disposed at an angle to the bar so that when the roller is moved in one direction it is carried into clutching engage ment with the edge of the bar, see Fig. jHTI.

The housing member has ear-like portions 15 which are struck upwardly to close the ends of the chamber in which the clutch lroller isvdisposed. rlhe clutch roller is thus supported for rotative and lateral movement, :it being positively moved laterally by vits rotation Aowing to the engagement of its toothed segment With the rack.

To actuate the roller l preferablyV provide lit with an opening 16 adapted to receive the key l1.7, the opening being .liattened on one side and .the ykey correspondingly lattened so .that the roller is rotated by turning the key.

Theadjusting member is provided with a slot-like 'opening 18 above the roller to permit the key beingfengaged and to permit its lateral movement as the roller travels to and from its engaging position.

With 4the .parts thus arranged the stress on "the y.binding vstrips tends to engage the clutch more tightly.

By providing the rack and segment arrangement the clutch roller is positively actuated Vto and from its engaging position.

In Ithe modified Vform of my invention shovvnin Figs. VI to IX, inclusive, the clutch `roller 19 `is smooth on its periphery. ltshousing or support 21 is provided with a smooth inclined Way disposed oppositely to the bar so that the roller is forced into clutching engagement with the bar. The Way portion 2O is, in this embodiment, formed integrally with the housing or sup- .portmemb'er 21, (see Fig. DQ.) the housing member having' an offset therein constituting .the Way. iIn thisembodimentihe roller is formed With acentralopening 22adapted .to :receive ,a key 23 [having a bit or tang adapted -tofsvving Within the roller and carry it .laQra-lly. Thehousing or support member is provided Witha hole f2ifor `thelower end .of thefgkey stem. fThe adjusting member isnmvided-vrith:;akey opening `25.

.. Leanser In the modification shown in Fig. X the bar 26 is toothed on its edge With Which the roller coacts. This insures a very firm clutching action between the roller and bar, although l do not lind it an essential in practice. The adjusting member 6 is slotted at 27 so that a pointed instrument may be introduced to shift it to and from engaging position.

ln the modification shown in Fig. XI, the roller 28 is toothed to coact With the toothed bar 26.

ln the modification shown in Figs. XII and XIII the clutch member 29 is in the form or a wedge block which is supported to coact with .the bar 7 substantially in the same manner'fas the yroller clutch.

To facilitate the adjustment-of the clutch member 29 its Way is provided With rollers 30.

lith the parts thus arranged, the binder may be quickly adjustedand is eiectively-retained in its adjusted position.

With the several embodimentsiof -my in` vention illustrated and described -I Vbelieve that the application or adaptation thereof to various forms of binders Will be readily understood by those skilled `in the art ,to Which my invention relates.
